CLEARER FOR DRAWING-ROLLS.

Specification of Letters Patent.

Patented Jan. 4, 1916.

Application filed .Tanuary 9,1915. Serial No. 1,423.

To all whom it may concern:

Be it known that we, PHILIP G- WARE, ALBERT GASTONGUAY, CHARLES J. LINDER- son, JAM S E. FARRELL, and WILLIAM S. VOODBURY, citizens of the United States, and residents of Newburyport, county of Essex, and State of Massachusetts, have invented an Improvement ,in Clearers for Drawing-Rolls, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

The invention to be hereinafter described relates to roll clearers for spinning and other textile machines, and more particularly to clearers of the double cone type.

As well understood by those skilled in the art, when a roving or other rope-like form of loosely assembled fibers are passed between rollers, as for instance, the draw ing rolls of spinning machines, much lint, fly, dirt, and the like collects upon the cylindrical surface of the roll and upon the usual cap-bars which are interposed between the roll sections; and various means have been suggested for clearing the rolls of this objectionable accumulation. Among these suggested means has been a double cone provided with a shiftable weight, which was intended to hold one end of the double cone depressed as the cone traveled lengthwise of the rolls in one direction, and at. the limit of such travel, to be shifted longitudinally of the cone to depress the opposite end and cause the cone to travel in the opposite direction longitudinally of the rolls. The shifting movement of the weight.

has usually been efiected by hand, and in some cases, attempts have been made to provide automatic means for this purpose, but such attempts have not been practically successful or acceptable, because they have either depended upon the endwise movement of the cone itself to efiect the relative longitudinal movement of the weight and cone, or have introduced undesirable and complicated mechanism operating independent of the cone itself, and consequently.

unreliable.

WVith the above generally-stated facts in view, the aims and purposes of the present invention are to provide a double cono clearer which shall be simple in construction and practically eflicient in operation,

, and wherein the r'otative movement of the cone itself is rendered efiective for causing the coneto be automatically tilted at each end of its traverse toshift the weight and enable the cone to reverse the directionof its movement longitudinally of the rolls.

The characteristics and important features of the present invention will best be made clear from the following description and accompanying drawing of one form of means for carrying the invention into prac tical effect, it being understood that the in vention is not limited to the particulars thereof, but in its true scope is defined by, the .claims. v i In -the'drawings:-'Figure 1 is a plan view of sufiicient portions of a spinning or other fiber-treating machine to make clear the operation of the present invention associated therewith, some of the parts being broken away, or omitted for 'clea'rness of illustration; F 2 is a front View Iof the parts shown by Fig. 1, illustrating the double cone clearer, substantially at one end of its longitudinal movement and about to have its lower end raised to tilt the cone in the reverse direction; Fig. 3 is a diagrammatic side view showing one end of the cone being raisedby rotative movementof the cone'itself; Fig. 4 is a detail View of the cone tilting ladder, showing the cone and rolls in dotted lines; and Fig. 5v is a longitudinal section of the cone detached.

The machine frame may be of the usual character found in spinning or other textile machineswhich are provided with drawing or like rolls, and in the present illustration it is shown as provided with portions 1 having suitable bearings for the rolls 2, 3, and 4. These rolls may be of any appropriate type between which and the usual lower rolls, not shown, the sliver, roving, or other rope-like character of fiber may be passed, but in the particular form illustrated, the back roll '2 is larger than the intermediate and front rolls 3 and 4, respectively. In

like substance 6, to which lint, fly, and dirt, etc., is adapted to adhere. conical end portions the cone is preferably provided with a series of brushes 7 formed of suitable bristles. These may be provided at suitable intervals about the largest part of the double cone, and if desired, the clearer cloth or like covering 6 may be omitted at the belt of bristles forming a plain zone 8, but the invention is not restricted in this respect. If used, the brushes 7 serve to effectively loosen and detach or partly detach much of the lint, fiy and dirt from the rolls.

Extending longitudinally through the double cone, is an opening which may be of tubular form to provide a runway for a traveling weight. In the illustrated form of the invention, the longitudinal opening is shown as provided by a tube 10 adapted to receive one or more movable weights 11.

From the construction thus far described, it will be apparent that if the double cone be placed upon the rolls, as indicated in Figs. 1 and 2, and have one of its ends depressed, the weight or' weights Wlll gravltate toward the depressed end and maintain said end in depressed position, so that upon rotation of the rolls and cone, as usual, the latter will travel longitudinally along the rolls with the depressed end of the cone leading. WVhen the cone has thus traveled longitudinally of the rolls to one side of the machlne or to one end, of the rolls, it is desirable that the cone be tilted into the reverse position, that is, the end that was before depressed should be raised and the end that was raised should be depressed to thereby cause the cone to travel toward the opposite side of the machine, or the other end of the rolls. To this end, the present invention contemplates means operative by or through the rotative movement of the cone as 1t completes its longitudinal traverse of the rolls, to effect the change in the tilted position of the cone; and one form of such means that has been found practically efficient, will now be described.

Mounted at each end of the double cone 1s a pin or spur wheel, the pins or spurs of which are adapted to engage devices at the end of the cone traverse and by rotative movement of the cone itself, caused by the rotation of the rolls, raise the depressed end of the cone, thereby causing the weight or weights to gravitate toward and thereafter to hold the other end of the cone depressed, as the cone travels longitudinally toward the other side of the machine.

The pin or spur wheels may be variously formed, but as shown, each comprises a cap piece 12 secured to and closing one endof the tube 10. A screw threaded connection between the cap pieces 12 and the tube 10 affords a convenient and good practical Between the form of union, and at the same time permits ready access to the interior of the tube for removing and replacing the weights 11. Each cap piece 12 has a series of pins or spurs 13 and extending longitudinally of the cone beyond the pins or spurs 13 is a finger or projection 141 for a. purpose that will presently appear.

Mounted at each side of the machine or at the ends of the rolls, is an arm 15 having a series of lugs or projections 16 suitably spaced apart and adapted to be successively engaged by the pins or spurs 13 as the cone rotates when it has reached the limit of its longitudinal movements in one direction. The characteristic action or law of operation of the pin or spur wheels and the arms 15 is such, that the end of the double cone, the pin or spur wheel of which is brought into coacting relation with one of said arms, is progressively lifted as the cone rotates until the weight or weights gravitate toward the opposite end of the double cone, whereupon the cone commences its travel longitudinally of the rolls toward the opposite side of the machine.

The lugs or projections 16 may be variously formed, but are here shown as pins secured to and projecting from the plate 15, and inasmuch as the end of the cone which is being lifted moves in a curved path, it is expedient to make the pins 16 progressively longer from the bottom toward the top of the plate 15 to insure positive engagement of the spurs 13 therewith as the end of the cone is raised; and to the same end, the plate 15 is preferably curved to correspond or substantially correspond with the path of movement of the end of the cone, as indicated in Fig. 3.

In order that the pin or spur wheel at the end of the cone may be maintained in cooperative relation with the plate 15 and its lugs or projections 16, means are provided to prevent sidewise movement of the end of the cone as the pins or spurs 13 progressively climb up the plate. As one means to this end, the plate 15, which for identification may be termed a ladder, is provided with a slot 17 which is engaged by the finger 1 1 of the pin or spur wheel, as the depressed end of the cone reaches the end of its travel, and said finger rides upward in said slot as the end of the cone is raised.

Various changes may be made in the details described without departing from the true spirit of the invention, aswe believe ourselves to be the first in this art to effect automatically tilting movement of a double clearer cone at the end of its traverse by rotative movement of the cone itself, but the means described have been found well adapted to carry the invention into practical effect. By making the cap pieces 12 of the form shown, the hollow portion thereof enables the weight or weights, which are preferably metal balls, to find a seat in each cappiece beyond the actual end of the cone, as shown by dotted lines in Fig. 3.
